Urgent Evoke

A crash course in changing the world.

Power Shift - Act


Design a new way to power something you use everyday.

Take a look around you. Something YOU use or do every day could be powered differently.

Your challenge this week is to DESIGN A NEW WAY TO POWER something you use everyday. Maybe it's your mobile phone. Maybe it's the light you use to read at night.

Your solution should be cheaper, or more sustainable, than your current power source.

It's an ambitious challenge -- but you're an EVOKE agent. You know that even if you fail, you can learn from your efforts... and maybe even inspire someone along the way.

Your objective: Design a new way to power something you use every day.

Share your design in a blog post, video or image. For legendary honors, make your idea real -- and show us in photo or video your brand new power source in action!

This objective is worth +10 resourcefulness.

Get credit for your evidence! After you submit your evidence in a blog post, photo or video, go to the newly posted evidence page and log your evidence for this objective. Then you'll receive credit on your profile page!

Everyday people wash their hands and every time you was your hands, it produces energy in the entire building for the wh*** day.

I brush my hair everyday, so my invention is a brush connected to an outlet. Whenever you brush your hair it sends electricity to your house or any electronics. This invention will be very affective to many people and I hope this item will make a huge difference in the future.

By thinking about something I use every, I notice that I have not so much things I could power on a cheaper way. So I start thinking about my equipment at work and at the university. There I could find something.
I work every day with a laptop for the study or for the work. I think it could be a way to power a laptop by an dynamo. After sitting so much before a laptop it is a nice alternation to power a laptop by using a dynamo. The dynamo must not be used by hand, it could also used with a feet-pedal so that I can work by the way.
If the weather is fine enough, I prefer to sit outdoor to do my work. Additional I could power the laptop by solarenergy. While I am working indoor with the laptop I could use my own little hydropower station. It could work with a pump like a pump to clean the ground of an aquarium. On that way could arise a hydrologic cycle, which driving a water wheel that is connected with a dynamo, to produce energy without using electric-energy for the pump. The produced energy could saved in a storage battery or be used for direct loading. If there is used a storage battery you can also power different equipment like a mobile phone, a flashlight or a radio.

For this week challenge I thought about a simple way to power something of my everyday life. Each day, if the weather is fine, I am using my bike. Recently when I cycled and the sun set I had to turn on the light. On my old bike the light is generated by a dynamo. At this moment I remembered of a generator flashlight my father used a while ago. This principle to generate electricity only with muscle power has been already transferred to different areas of application (here flashlights, but also chargers and radios). On that basis I thought it would be very effective to use mechanical supercharging for example for MP3 player / iPods. Nearly every person has such a device and uses it every day or at least frequently. It is also conceivable to use that approach for a lamp to read in bed in the evening. This dynamo technology is of course very easy and favorable, independent of electricity and battery and furthermore very efficient. Different constructions may be used: a crank, hand gear, or flywheel is quite possible. Besides these possibilities you have to think about the use of incandescent lamps or LEDs. Incandescent lamps are cost-effective, reliable and generate sufficient light. But they are rather inefficient. Nearly 98 percent is lost in heat. Furthermore a limited life span is conspicuous. In contrast LEDs are very durable (about 10000 hours). But determining is the low-energy consumption and the luminous efficacy for example for a 'generator reading lamp'.

I heard about this new idea where you generate electricity from buried carbon.
Jamming carbon deep underground has long been a proposed solution to our emissions problems, but it's expensive and rarely used. Now we can use the Earth's heat to make that gas work for us.

I think that electric bikes, should run on solar-enegy. You could defently do that, and that would be a small step, into becoming more sustainable.

i want to make a perendev magnetic motor that generates electricity from magnets propelling from each other on a shaft that turns a generator. heres what it looks like

Taking a shower with water heated from the sun is an easy way to power something you use everyday, and its done naturally. Just fill a water bladder and let it sit in the sun all day, or until its at a desired temperature. You only have a small amount of water to use compared to the shower in a bathroom, but its just as hot and lasts about fifteen minutes if you use the water conservatively. If this was the only water used for bathing, a family’s water bill would be lowered significantly.

We make many of the things we used to purchase. So we're recycling the containers we do need to buy and reducing overall purchases. This takes some team work, and helps us develop our relationship with each other in the process. Our biggest change as far as power use is concerned is the back up kerosene heater we started using last year. O.K. not so amazing but it's off the grid :)

I've already started on this one. Renovating an old house, I decided to put in a cool duct to lead to a cooling cupboard for fruit and vegetables. This should mean I can downsize the refrigerator, and hopefully phase it out eventually once I set up a pot in pot fridge to keep the milk cold. (http://en.wikipedia.org/wiki/Pot-in-pot_refrigerator) I have set up a 6m long terracotta pipe, 230mm in diameter. It runs to bottom of the cool cupboard from below the floor in the coldest part of the house(southern side in the southern hemisphere) and is partially earth buried, which I hope will aid in cooling the air. The plans I found suggest a minimum of 300mm diameter pipe of any material, but this size was just too big for me to manage. The cupboard when built will be insulated, with wire baskets holding food and allowing air to pass through. Air will be drawn up through the cupboard by a spinning vent. This may stretch the definition of powering something, but it through utilising passive cooling techniques, it will dramatically cut down on energy use in my household.

i use my i pod everyday and i listen to music through out the wh*** day so i would have a generator hooked up to my ipod and that would generate enough power for everything.
Comment by Jarrod Alagao on April 21, 2010 at 10:43pm
this is a wacky/cool thought but how cool would it be to own a couple of electric eels and have them power up your home? These suckers generate up to 600 volts of electric, just imagine the possibilities! I've always wanted to say that I charged my phone/ipod/laptop through my pet electric eel. Talk about a conversation starter...
Comment by Joseph Cardillo on April 21, 2010 at 7:30pm
Use one electric generator hooked up to a small water fall that continuously gets power from the running water.

With architect friend we can lower energy of a house without solar plot : )
Comment by Azor, Jack Eyram on April 14, 2010 at 2:12pm
Ghana depends on only hydroelectric power and this is the reason why we always have our lights going off during the dry season. i think the most effective way we can think supplement this source is by solar energy, we have a lot sun shrine her in Ghana during the dry season and i think all these energy could be collected and stored in a high capacity batteries which could take very very high voltage of power which we can use to supplement the hydroelectric source. So simply, just as a tank is use to reserve our waters, we need high capacity batteries to tap the sun rays. we have to develop one.

i am an artist and i don't have the means to invent an electricity, but i have ideas abut how power could be managed, now i think i need help. advice as to what i should do. thanks
Comment by Neil Spurgeon on April 13, 2010 at 1:30pm
I use my MP3 player every day and change the battery at least once a fortnight - I have today purchased a pedal powered battery recharger which will sit under my desk at work and can be operated whilst I am using my computer to charge one, or more, rechargable batteries

You can reduce the energy by unpluging plugs and turn off the room lights if you are not using that room
Comment by nomadHAR on April 11, 2010 at 2:26am
let me suggest an alternative mission:

Urgent Evoke agents, see if you can reduce your energy usage in your electric bill by 25%. it is much easier than you might think.

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.

Where I will be in ten years.

Ten years from now I will be in a political job assisting with people in the midlands of South Carolina particularly the rural working class and farmers. As the class of people that feed the nation I find that it is imperative that we assist with making sure they produce as much food as possible. I would like to support local scientists as well that are leading in research on how to produce food more efficiently. I will also be participating in missions to foreign countries to help people with…See More
